1 Claim.

This invention relates to a safety razor blade holding device.

The object of this invention is to provide a holder for a standard formof double edged razor ".5l blade, the holder being so constructed thatthe blade may quickly and readily be attached thereto andremovedvtherefrom, the blade being so held on the holder whereby thedevice may be used for shaving by one who shaves with a straight razorin order to thus dispense with the troublesome honing required in theuse of a straight razor necessitating skill and the eX- penditure oftime.

Other objects of the invention relate to the safety blade holder devicebeing adaptable for use for stropping razor blades, as a utility knifein the home, ofce or shop, and for a multitude of other purposes.

Important objects of the invention are thus to provide a holder of thecharacter described, which will accurately and rigidly dispose of theblade at the proper angle on the holder for shaving or stroppingpurposes, and which blade is releasably held in position by a springbacking plate, the Whole device embodying but two parts in addition tothe razor blade, which may be effectively operated even by unskilledpersons, and which may be conveniently and quickly operated to secure ablade or to release the latter therefrom.

In the accompanying drawing in which similar and corresponding parts aredesignated by the same characters of reference throughout the severalviews in which they appear:-

Figure 1 is a side View of the safety razor blade holder constructed inaccordance with the present invention.

Figure 2 is a front edge elevational view of the same.

Figure 3 is a separated View showing the safety razor blade mountingportion of the holder and the spring backing plate in position prior toassembly of the same on said holder.

Referring in detail to the drawing, I denotes the safety razor bladeholder comprising a handle II, and a Xed clamping jaw I2 formed integraltherewith at one end thereof, the entire holder Ill being preferablyformed of metal of any desired nish and character. The fixed clampingjaw I2 is made slightly wider than the width of the handle II as shownand is provided with a depressed flat jaw surface I3 having at each endthereof a shoulder I4. The distance between the shoulders I4 is such asto be equal to the length of a standard form of double edge razor -bladeI5 shown, see Figure 3, seated on the jaw surface I3, with thetransverse edges thereof engaging the shoulders I4.

Formed integral with the jaw I2 or otherwise fixed thereto are a pair oflongitudinallyV spaced i centering pins i6 arranged to one side of thecenter longitudinal plane of the jaw I2 and projecting above the jawsurface I3. The size oi the pins I6 are such as to snugly t within theconventional centering openings in the razor blade I5 whereby toproperly position the same on the jaw I2. It will be noted that theposition of the pins I6 on the jaw I2 is such that with the razor bladeI5 centered thereby, only one edge portion |50; of the razor blade I5will project beyond, what is the forward edge I 2a of the jaw I2, asclearly shown in Figure 3, the other edge I5b of the razor blade I5lying flush with the back edge I2b of the jaw I2 so as to be completelycovered thereby,

The opposed sides of the pins I6 are each notched or grooved as at IIforv a purpose to be hereinafter described.

In order to lock the razor blade I5 to the holder I0 there is provided aremovable clamping jaw I8 formed to provide a spring backing plate. Theremovable clamping jaw I8 is formed of spring steel, of a length andwidth slightly less than the length and'width of the razor blade I5. Atone long edge of the removable clamping vjaw I8 there is formed a pairof longitudinally spaced re-entrant cut-away portions I9 to denne acentral tongue 20 having parallel transverse edges 2|, the portionsadjacent to each edge 2I being curved upwardly as at 22 to provide aspring bow. The length of the tongue 2U or spring bow from thetransverse edge 2l to transverse edge 2l is equal to the distancebetween the opposed bases of the grooves Il in the pins I6.

The width of the cut-away portions I9 is such as to receive therein thesolid portions of the pins I6, in the assembly of the removable clampingjaw I8 with the fixed jaw I2, the bottoms of said cut-away portions I9being curvedas at 23 to provide limiting stops for inward movement ofsaid jaw I8.

'I'hus with a razor blade `I5 positioned on the xed clamping jaw I2, seeFig. 3, the same is clamped thereto by the removable spring clamping jawI8 which is assembled by inserting the tongue 20 with its upwardlycurved ends 22 into the grooves I'I of the pins I8. The curvature ofsaid curved ends 22 is such that the same will react against the headsIlia of the pins I6, see Figure 2 to set up a spring pressure in thebody of l the removable clamping jaw I to tightly press the same againstthe razor blade l5 thus maintaining the same resiliently clamped to thexed jaw I 2 in the manner readily apparent. The Width of the removablejaw I8 is such as to coact with the edge l2b of the fixed jaw I2` tocompletely enclose the edge |51) of the razor blade as shown inFigure 1. l

It Will thus be seen that an extremely simple and eicient holder for asafety razor blade has been provided. It is to be understood, however,that the showing thereof is merely illustrative of the embodiment of theinvention, and that the actual needs of manufacture and practice maynecessitate certain mechanical variations. It is therefore, not intendedto limit the inventionv to the disclosure thereto herein illustrated,but rather to dene such limitations in the'clai'niA hereunto appended.

Having thus described my invention, I lclaim as side 'of said xedclamping jaw extending the full Width thereof and defining at each end atransing said blade that only one edge thereof Will extend beyond thelongitudinal edge of said clamping jaw nearest to said pins, and aremovable clamping jaw rectangular in shape of the same Width as saidclamping surface but of less length thereof comprising an intermediatetongue defined by a pair of longitudinally spaced transverse slotsextending inwardly from one longitudinal edge thereof, each transverseend of said tongue being bowed upwardly to provide a resilient holdingportion, said slots being adapted to slidably receive said pins and saidresilient holding portions engaging the underside of the heads of saidpins whereby to securely clampy
